The reactions described hereinabove and hereinbelow are carried out in a manner known per se, for example in the absence or, conventionally, in the presence of a suitable solvent or diluent or a mixture of these, the process being carried out, as appropriate, with cooling, at room temperature or with heating, for example in a temperature range from approximately -80°C to the boiling point of the reaction medium, preferably from approximately -20°C to approximately +150°C and, if required, in a sealed vessel, under pressure, in an inert gas atmosphere and/or under anhydrous conditions. Typical reaction conditions can be found in the examples. Examples of nucleofugic radicals Z or Z' are: fluorine, chlorine, bromine, iodine, C j -Cgalkylthio, such as methylthio, ethylthio or propylthio, C r C 8 alkanoyloxy, such as acetoxy, (halo-)C 1 -Cgalkanesulfonyloxy, such as methanesulfonyloxy, ethanesulfonyloxy or trifluoromethanesulfonyloxy, or substituted or unsubstituted phenylsulfonyloxy, such as benzenesulfonyloxy or p-toluenesulfonyloxy, and furthermore also hydroxyl.

Examples which may be mentioned are sodium hydroxide, sodium hydride, sodium amide, sodium methanolate, sodium carbonate, potassium tert-butanolate, potassium carbonate, lithium - diisopropylamide, potassium bis(trimethylsilyl)amide, calcium hydride, triethylamine, triethylenediamine, cyclohexylamine, N-cyclohexyl-N,N-dimethylamine, N,N-diethylaniline, pyridine, 4-(N,N-dimethylamino)pyridine, N-methylmorpholine, benzyltrimethylammonium hydroxide and l,8-diazabicyclo[5.4.0]undec-5-ene (DBU). The reactants can be reacted with each other as such, i.e. without an addition of a solvent or diluent, for example in the melt. In most cases, however, the addition of an inert diluent or solvent or a mixture of these is advantageous. The following may be mentioned as examples of such solvents or diluents: aromatic, aliphatic and alicyclic hydrocarbons and halohydrocarbons, such as benzene, toluene, xylene, chlorobenzene, bromobenzene, petroleum ether, hexane, cyclohexane, dichloromethane, trichloromethane, dichloroethane or trichloroethane; ethers, such as diethyl ether, tert-butyl methyl ether, tetrahydrofuran or dioxane; ketones, such as acetone or methyl ethyl ketone; alcohols, such methanol, ethanol, propanol, butanol, ethylene glycol or glycerol; esters, such as ethyl acetate or butyl acetate; amides, such as N,N-dimethylformamide, N,N-dimethylacetamide, N-methylpyrrolidone or hexamethylphosphoric triamide; nitriles, such as acetonitrile; and sulfoxides, such as dimethyl sulfoxide. Bases employed in excess, such as triethylamine, pyridine, N-methylmorpholine or N,N-diethylaniline, can also act as solvents or diluents. The reaction is advantageously carried out in a temperature range from approximately 0°C to approximately +180°C, preferably from approximately +20°C to approximately +130°C, in many cases at the reflux temperature of the solvent used. Alternatively, the reaction can be carried out with phase-transfer catalysis in an organic solvent, for example methylene chloride or toluene, in the presence of an aqueous alkaline solution, for example sodium hydroxide solution, and of a phase transfer catalyst, for example tetrabutylammonium hydrogen sulfate. A compound I which can be obtained according to the invention or by another route or, if appropriate, a tautomer of this compound, can be converted into another compound I in a manner known per se by replacing one or more substituents of the starting compound I in the customary manner by another substituent. For example, - substituents which do not contain halogen, or unhalogenated aromatic or heteroaromatic part-structures of rings can be halogenated to give halogen-containing substituents or halogenated aromatic or heteroaromatic part-structures of rings; - halogen substituents can be exchanged for other substituents, such as cyano, alkylthio or alkoxy substituents; - alkanoyl, benzoyl or sulfonyl substituents can be exchanged for easily exchangeable hydrogen or - N-hydrogen can be exchanged for N-alkyl, N-benzyl, N-aryl, N-heteroaryl, N-alkanoyl, N-benzoyl or N-sulfonyl; - sulfides can be oxidized to give sulfoxides and sulfones; or - carbonyl groups can be sulfated to give thiocarbonyl groups. The invention relates to the pure isomers and to all isomer mixtures which are possible. The invention also relates to novel starting materials and intermediates used for the preparation of the compounds of the formula I, to their use and to processes for their preparation. The compounds of the formulae II, Nπ and IX can be prepared by known methods as shown in the equation. In this equation, A, Rι 0 , Z, M and X are as defined above.

The preparation of the compounds of the formula IX, DC, XI and XII is described, for example, in Swiss Patent Application Nos. 509/93-0 (date of application: February 18th, 1993), 617/93-3 (date of application: March 2nd, 1993) and 1788/93-2 (date of Equation oxidation thionation thionation oxidation R10-Z IX application: June 16th, 1993). The compounds of the formulae III, IV, V and VI are known or can be prepared by known methods. Pyrimidines which are amino-substituted in the 4-position have already been disclosed, for example in Patent Application No. WO 92/08704. The compounds I of the present invention differ structurally from these known compounds in a characteristic manner; moreover, the compounds of the formula I of the present invention have an unexpectedly powerful microbicidal, insecticidal, nematicidal and acaricidal activity. Protection of the plants may take place by direct action on the pests and also by activating and stimulating the plant's defence system (immunization). The compounds of the formula I can be used in the agricultural sector and in related fields as active ingredients for the control of plant pests. The active ingredients according to the invention are distinguished by a powerful activity at low rates of concentration and by the fact that they are well tolerated by plants and environmentally friendly. They have highly advantageous curative, preventive and systemic properties and can be used for protecting a large number of crop plants. Using the active ingredients of the formula I, the pests which are found on plants or parts of plants (fruits, flowers, foliage, stalks, tubers, roots) of a range of crops of useful plants can be contained or destroyed, and parts of plants which are formed at a later point in time are also left unharmed, for example by phytopathogenic microorganisms. Compounds of the formula I can also be used as seed-dressing agents for the treatment of plant propagation material, in particular seed (fruits, tubers, kernels) and nursery plants (for example rice) for protecting them against fungal infection and against soil-borne phytopathogenic fungi. The compounds I are active for example against phytopathogenic fungi from the following classes: Fungi imperfecti (for example Botrytis, Pyricularia, Helminthosporium, Fusarium, Septoria, Cercospora and Alternaria) and Basidiomycetes (for example Rhizoctonia, Hemileia, Puccinia). Moreover, they are active against the classes of the Ascomycetes (for example Venturia and Eiysiphe, Podosphaera, Monilinia, Uncinula) and of the Oomycetes (for example Phytophthora, Pythium, Plasmopara). Moreover, the compounds I according to the invention are valuable active ingredients for controlling pests of the order of the Acarina and the classes of the Insecta and Nematoda in agricultural crop plants and ornamentals, in particular in cotton, vegetable and fruit crops, in forests, in the protection of stored products and materials and in the hygiene sector, and of animal pests, in particular in domestic animals and productive livestock. They are active against a range of development stages. Their activity becomes apparent from immediate destruction of the pests or only after some time has elapsed, for example during molting, or from markedly reduced oviposition and/or hatching rates. The Acarina include, for example, Boophilus spp. and Tetranychus spp., the Nematoda include, for example, Heterodera glycines, and the Insecta include, for example, Nilaparvata lugens, Plutella xylostella and Musca domestica. Examples of target crops for the use in crop protection within the scope of the invention are the following types of plants: cereals (wheat, barley, rye, oats, rice, maize, sorghum and related species); beet (sugar and fodder beet); pome fruit, stone fruit and soft fruit (apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries and blackberries); leguminous plants (beans, lentils, peas, soya beans); oil crops (oilseed rape, mustard, poppies, olives, sunflowers, coconut, castor, cocoa, groundnuts); cucurbits (pumpkins, cucumbers, melons); fibre plants (cotton, flax, hemp, jute); citrus fruit (oranges, lemons, grapefruit, mandarins); vegetables (spinach, lettuce, asparagus, cabbages, carrots, onions, tomatoes, potatoes, red pepper); the laurel family (avocado, cinnamon, camphor), and plants such as tobacco, nuts, coffee, egg plants, sugar cane, tea, pepper, vines, hops, the banana family, latex plants and ornamentals. Active ingredients I are conventionally used in the form of compositions and can be applied to the area or plant to be treated simultaneously or in succession with other active ingredients. These other active ingredients can be, for example, fertilizers, trace element mediators or other preparations which have an effect on the growth of plants. Other substances which can be used are selective herbicides and also insecticides, fungicides, bactericides, nematicides, moUuscicides or mixtures of a plurality of these preparations, if appropriate together with other carriers, surfactants or other application-enhancing additives conventionally used in the art of formulation. Suitable carriers and additives can be solid or liquid and are those substances which are expedient in the art of formulation, for example natural or regenerated mineral substances, solvents, dispersants, wetting agents, adhesives, thickeners, binders or fertilizers. A preferred method for applying an active ingredient of the formula I or an agrochemical composition which comprises at least one of these active ingredients, is applying it to the foliage (foliar application). The frequency and rate of application will depend on the risk of infestation with the pathogen in question. Alternatively, the active ingredients I can also reach the plant via the soil through the root system (systemic action), by drenching the locus of the plant with a liquid preparation or by incorporating the substances in solid form into the soil, for example in the form of granules (soil application). In the case of paddy rice, such granules can be metered into the flooded rice field. However, the compounds I can also be applied to the seed kernels for seed treatment (coating) by soaking the kernels or tubers in a liquid preparation of the active ingredient or by coating them with a solid preparation. The compounds I are employed as pure active ingredients or, preferably, together with auxiliaries conventionally used in the art of formulation. To this end, they are expediently processed in a known manner, for example to give emulsion concentrates, spreadable pastes, ready-to-spray or ready-to-dilute solutions, dilute emulsions, wettable powders, soluble powders, dusts or granules, for example by encapsulation in, for example, polymeric substances. The methods of application, such as spraying, atomizing, dusting, scattering, brushing on or pouring, as well as the nature of the compositions are selected to suit the intended aims and the prevailing circumstances. Advantageous rates of application are, in general, 5 g to 2 kg of active ingredient (A.I.) per hectare (ha), preferably 10 g to 1 kg of A.L/ha, in particular 20 g to 600 g of A.L/ha. When used as seed-dressing agents, it is advantageous to use dosage rates from 10 mg to 1 g of active ingredient per kg of seed. The formulations, i.e. the compositions, preparations or combinations which comprise the active ingredient of the formula I and, if desired, a solid or liquid additive, are prepared in a known manner, for example by intimately mixing and or grinding the active ingredient with extenders, such as solvents, solid carriers and, if appropriate, surface-active compounds (surfactants). The following are possible as solvents: aromatic hydrocarbons, preferably the fractions C 8 to Cι 2 , for example xylene mixtures or substituted naphthalenes, phthalic esters, such as dibutyl phthalate or dioctyl phthalate, aliphatic hydrocarbons, such as cyclohexane or paraffins, alcohols and glycols as well as their ethers and esters, such as ethanol, ethylene glycol, ethylene glycol monomethyl ether or ethylene glycol monoethyl ether, ketones, such as cyclohexanone, strongly polar solvents, such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or dimethylformamide, and epoxidized or unepoxidized vegetable oils, such as epoxidized coconut oil or soya oil, and water. Solid carriers which are used for example for dusts and dispersible powders are, as a rule, ground natural minerals, such as calcite, talc, kaolin, montmorillonite or attapulgite. To improve the physical properties, it is also possible to add highly-disperse silica or highly-disperse absorptive polymers. Possible paniculate, adsorptive carriers for granules are porous types, such as pumice, brick grit, sepiolite or bentonite, or non-sorptive carrier materials, for example calcite or sand. Moreover, a large number of pregranulated materials of inorganic or organic nature can be used, such as dolomite or comminuted plant residues. Suitable surface-active compounds are non-ionic, cationic and/or anionic surfactants which have good emulsifying, dispersing and wetting properties, depending on the nature of the active ingredient of the formula I to be formulated. Surfactants are also to be understood as meaning mixtures of surfactants. Suitable anionic surfactants can be either so-called water-soluble soaps or water-soluble synthetic surface-active compounds. Examples of non-ionic surfactants which may be mentioned are nonylphenol polyethoxyethanols, castor oil polyglycol ether, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethylene ethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Fatty acid esters of polyoxyethylene sorbitan, such as polyoxyethylene sorbitan trioleate, are also suitable. The cationic surfactants are, especially, quaternary ammonium salts which have at least one alkyl radical having 8 to 22 carbon atoms as N substituent and lower, free or halogenated alkyl, benzyl or lower hydroxyalkyl radicals as further substituents. Other surfactants conventionally used in the art of formulation are known to the expert or can be found in the relevant specialist literature. As a rule, the agrochemical preparations comprise 0.1 to 99 percent by weight, in particular 0.1 to 95 percent by weight, of active ingredient of the formula 1, 99.9 to 1 percent by weight, in particular 99.8 to 5 percent by weight, of a solid or liquid additive, and 0 to 25 percent by weight, in particular 0.1 to 25 percent by weight, of a surfactant. While concentrated compositions are more preferred as commercially available goods, the end user will, as a rule, use dilute compositions. The compositions can also comprise other additives, such as stabilizers, defoamers, viscosity regulators, binders or adhesives, and also fertilizers or other active ingredients for achieving specific effects. The examples which follow illustrate the invention described above without limiting its scope. Temperatures are given in degrees centigrade. The following abbreviations are used: Ac = acetyl; Et = ethyl; i-Pr = isopropyl; Me = methyl; Ph = phenyl; Pr = n-propyl; Bu = n-butyl; m.p. = melting point; ds = diastereomer, reg = regioisomer. "NMR" means "nuclear magnetic resonance spectrum"; MS = mass spectrum. " " means "percent by weight", unless a different unit is used for indicating the relevant concentrations. Examples for the preparation of the compounds according to the invention Example H- la: 0.9 g of 7-[l-(5-chloro-6-ethylpyrimidin-4-ylamino)ethyl]-3,4-dihydro-2 -methylthioquinoline and 0.86 g of 2,3-dichloro-5,6-dicyano-l,4-benzoquinone (DDQ) are introduced into 20 ml of absolute dioxane in a sulfonation flask at room temperature and the mixture is stirred for approximately 6 hours at 85-90°C. After cooling, the mixture is diluted with 100 ml of ethyl acetate and 30 ml of water, the organic phase is separated off, and the aqueous phase is then extracted twice using ethyl acetate. The organic phase is dried over sodium sulfate, the solvent is removed by distillation under a waterpump vacuum and the residue is purified by column chromatography on silica gel (eluent: n-hexane/tetrahydrofuran 3:1). 0.6 g of 7-[l-(5-chloro-6- ethylpyrimidin-4-ylamino)ethyl]-2-methylthioquinoline is obtained in the form of a white powder (m.p. 82-84°C). Other compounds which can be prepared analogously to the procedure described in Example H-la or using one of the abovementioned procedures are those listed in the tables below.
